I purchased 2 of the new 24" LG UltraFine 4K monitors, I have them installed side by side, the one of the left the whites look more "blueish" and the one of the right has "warmer" whites, I have attached a photo, what is the best way to calibrate the colors for them to be a match or at least better? Thanks

I have exactly the same issue with a pair of LG 21.5 Ultrafine, I tried adjusting color profiles unfruitfully, look better but not a perfect match. I am seriously thinking in buying a x-rite color checker to calibrate both monitors.

I'm wondering this as well. I recently picked up a second LG 27UD88-W, which is noticeably warmer than my other monitor. I was very happy with the default colors/temperature of my first monitor and so I never felt the need to have to calibrate it. The opposite is true with the second monitor though (i.e., the monitor on the left).


After changing the temperature of the monitor, I feel like it's closer to the one on the right but still not ideal. I currently have the temperature set to 7500K, which is much higher than the default value of 6500K. But does that mean I'm actually looking at a display that's 7500K or no would it be closer to 6500K when considering the naturally yellowish tint of this particular display? In other words, if I think I'm looking at a display that looks mostly normal am I really looking at something that may tend to induce eye strain more so because the temperature is set so much higher?


Regardless, even after adjusting the temperature, I still think the corners of the new display are noticeably warmer and darker than the rest of the display. This is not something that I notice on my other monitor. Is it worth trying to exchange the new monitor or am I just as likely to experience the same issue?


Lastly, does anyone have any recommendations for a bluetooth keyboard and mouse that I can easily use with both my Apple and Windows machines? Ideally, I'd like to be able to quickly switch back and forth between devices using just one keyboard and mouse.
